Why Air Quality Should be Your Top Priority During Coronavirus Outbreak

Natural ventilation is essential in virus and infection control


Let’s be real: the new coronavirus pandemic has disrupted all our daily lives – in one way or another. The novel virus dominates our headlines, travel is restricted, schools are being closed and events cancelled while the situation is rapidly evolving. In times of a global health crisis such as the one caused by COVID-19 it is staying calm and maintaining a positive attitude that will keep us sane.


It’s important to follow the preventative measures to protect yourself against the virus – such as washing your hands often and avoiding close contact. Another often over-looked factor in the disease prevention is something as simple as fresh air. We often take the air we breathe for granted, but as for airborne viruses, surrounding ourselves with fresh air might be the key to keeping our immune systems in top shape.



When it comes to viruses, studies show that higher outdoor air ventilation rates and better filtration can reduce the risk from influenza[1], rhinovirus[2], tuberculosis[3] and Sars [4].


It’s not surprising if you consider that most air contaminants are produced indoors, not outdoors – and are a result of human activity[5].


Therefore CO2 level in the air can be a great tool for assessing the overall air quality indoors. Growing evidence suggests that elevated levels of carbon dioxide or CO2 may pose direct risks for human health, including impaired immune system[6]. It’s especially important now when most of us are working from home – the CO2 level rises rapidly when more people are spending prolonged periods of time in the same room. So it is more important than ever to take care of the ventilation in your home in order to support your and your family’s immune resilience. Here is where a device such as Aranet4 can be a great tool to remind yourself to ventilate when it’s actually needed.


So what can you do to improve indoor air quality? Even if you don’t have a smart ventilation system in place, here are five easy things you can do to instantly improve airflow in your room. Whenever Aranet4 indicates that the CO2 level is about to become unhealthy:


1. Open a window allowing fresh air to flow into the room. For the best airflow it is recommended to open windows on two different sides of the room.

2. Remove any obstructions in front of the windows such as heavy curtains, blinds or furniture that can stop the airflow.

3. Open the window or windows in connecting rooms and leave the door open for at least 10 minutes.

4. Open the entrance door and/or door to the connecting rooms.

5. Turn on the ventilation. Check that the vents are open and there are no blockages in the ducts. Schedule maintenance if there are any issues.


Don’t wait until you start feeling drowsy or even sick to fix the airflow in your house or apartment. Take care of yourself and your loved ones before it’s too late!
